High Tensile Strength And Low Elgongation 2020 Black Biaxial Plastic Geogrid
Biaxial Plastic Geogrid Introduction
Plastic geogrid is a kind of polymer mesh material with square or rectangular shape formed by stretching. It can be divided into uniaxial tension and biaxial tension according to the different stretching direction. It is to punch holes on the extruded polymer sheet (mostly polypropylene or high density polyethylene) and then perform directional drawing under heating condition.
The unidirectional tension grid is only made along the length direction of the plate, while the bidirectional tension grid is made by drawing the unidirectional tension grid in the direction perpendicular to its length. In the manufacturing process of the plastic geogrid, the polymer will be reoriented with the heating extension process, which strengthens the bonding force between the molecular chains and achieves the purpose of improving its strength. Its elongation is only 10% ～ 15% of the original sheet.

Biaxial Plastic Geogrid Application
(1) The high tensile modulus of elasticity ensures that the geogrid can exert high tensile strength at low strain. (2) It has no deformation and good creep resistance under long time continuous load. (3) Large friction coefficient (mostly around 0.8) and strong force of stone, sediment and concrete are conducive to prevent slippage. (4) It is stable in chemical properties, resistant to acid, alkali, salt solution, or gasoline, diesel and other organic solvents, can not be decomposed by water, resistant to environmental stress fragmentation and microbial damage. (5) light weight, easy to transport, simple and convenient construction, low maintenance cost; aging resistance, bearing load, service life of more than 120 years; (6) wide range of uses, can be used for subgrade, retaining wall, dam, etc Building foundation, flight runway, etc.
Biaxial Plastic Geogrid Construction method
Construction method of two-way plastic geogrid: excavate subgrade bed, set sand cushion (height difference is not more than 10cm), roll into platform, lay geogrid, longitudinal axial direction should be consistent with the main stress direction, longitudinal lap 15-20cm, transverse 10cm, lap with plastic tape binding, and on the laid grid, every 1.5-2m with U-nails fixed on the ground, the laid geogrid should be timely backfilled with soil, The number of layers of geogrid laid depends on the technical requirements.
